CONTAINER.

Application led April 8, 1921. Serial No. 459,615.

To all lwhomV t may concern:

Be it known that I, HERBERT L. CARPEN- v Tun, a citizen of the UnitedStates, and a resident of the city of New York, boroughof Brooklyn, inthe county of Kings and State of New York, have invented a new andImproved Container, of which vthe following is a full, clear; and exactdescription.

This invention relates to containers, and has particular reference tocontainers which are collapsible as well as to the method of holding thecontainer closed under predetermined and continuing pressure. An objectof the invention is to provide a container for general use which isprovided with a body portion of sheet material which can be rolled intoshape in the form of a plurality of laminations which may or may not beheld together by adhesive, as desired, or may be formed and folded as inthe case of a rectangular body portion. Suitable heads of metal or othermaterial are provided to grip the upper and lower edges of the bodyportion with a sort of wedging or binding action to reinforce andstrengthen the body portion, and at the same time means are provided,extending between the body portion and the heads to hold the heads onthe body portion with e predetermined and continuing pressure.

Another object resides in the provision of means whereby thesecontainers can be collapsed to occupy very small space when not in use.

A further object resides in the provision of means whereby a containeris formed of elements which are collapsible and yet which at the sametime when assembled provide an extraordinarily compact, rugged andstrong device. j

A still further object resides in the pro- 4vision of means whereby thecontainer is not only strong and collapsible but is also absolutelytight, so as to permitl of the reception of ine material, such as iiouror metallic dust Another object resides in the particular constructionand arrangement of parts whichI are hereinafter described and claimedand shown in the accompanying drawings.

A further object of the invention is to provide such a structure thatthe heads and means for holding the heads together can be easilyassembled and disassembled and salvaged without damage, so that they canpermitting a great saving in the net material be reused with new bodyportions, thereby A cost of .shlpping 1n these containers. i

The invention in general comprises a hollow body portion, which may becurved or straight sided but which is shown in Figs. .1, 2 and 3 in theform of a cylinder, which 1s made up of a plurality of layers of rolledor composition sheet material, either of metal or liber or a combinationof both. These laminations may, if desired, be held together by a layerof adhesive between successive layers of laminations, thereby making asolid seamless body portion, although this is not necessary. When thelayers of sheet material arerolled together without adhesive, it ispreferable to provide simple fastemng means at each end of the sheet toengage the other laminations or layers and temporarily hold themtogether. Heads or cover portions, preferably although not necessarilymade lof metal, are provided to close the upper and lower ends of thebody portions. These heads are provided with tapered flange portionshaving a form similar to the form of' the edges of the body portion, andare adapted to engage therewith in a. wedging or clamping manner to bindthe edges of the body portion tightly together. Means are provided toforce and hold the heads on to the body portion under a predeterminedpressure, which results 1n a container or package which is exceedinglystrong and compact.

The invention is illustrated in the draw-l ings, of which- Figure 1 is atransverse vertical section through a container;

One of the preferred forms of my invention, as shown in Figs.- 1 to 9,inclusiye, comprises a hollow body portion 1 which is formed of aplurality of layers 2 of laminated material, which may be paper, thinsheet metal or a combination of both. These laminations are rolled inthis form under pressure in any suitable type of machine, and under someconditions they are provided with a layer such as 3 of adhesive materialbetween successive laminations.

Each end of this hollow container is adapted to be provided with aclosure portion 4 Which is in the form of a head made of metal or ofsome other suitable material, perhaps ber or paper. This head portion isprovided with a plurality of reinforcing corrugations or ribs 5 and isalso provided with a curved, tapered groove 6 which is formed along` theedge of the head between tapered flange of the groove 6 and 7 issimilar` ortions 7 and 7 The form etween the flange portions 7 to theform of the upper edges of the body portion 1 which the groove 6 1sadapted to engage. The center 8 of each head portion is flat andprovided with suitable apertures, one of which is adapted to receive thesquare shank 9 of a bolt. Between the head 10 of the bolt and the shank9, on the outside of one of the heads, is a washer 11. A pin 12 extendsthrough the shank 9 within "the container to hold the bolt within thecontainer. The body .portion 13 of the bolt is provided with threadssuch as 14 at the other end. This threaded ortion extends through asuitable aperture 1n the other head 8 and is adapted to receive a washer15 and a winged nut 16 thereon. By tightening the nutthe heads 4 may bedrawn tightly together over the upper and lower edges of the container.I desired, an aperture17 may be provided through the upper end of thebolt 13 so that a sealing wire may be passed therethrough. A

By tightening up the winged nut '16, a pres sure is exerted through thehead on the upper and lower edges of the container throughout theirlength and is exerted longitudinally on the laminations. By reason ofthe tapered groove the body portion is not only subjected to acompression but the uper and lower -edges of the laminations are boundtightly together. It is found that 12 is a perspective view of a recl'this results in an exceedingly strong package or container, capable ofstanding great stresses, due to this binding and clamping action.

In Fig. 1l the square shank ofthe bolt is, along its corner edges,provided with threads 18 with which a nut, such as 19, is adapted toco-operate This arrangement takes the place of the pin 12, and,moreover, is more likely tohold the body 13 of the bolt in an uprightposition so that the upper end of the bolt is maintained in properposition to facilitate the right placement ol' the upper head 4 on thebody portion.

As shown in Fig. 4, the laminations may be formed of a continuous sheetof material, sometimes made entirely of paper, and other times madepartly of metal, such as 20, and partly of paper, such as 21. The endsof the sheet may be provided with reinforcing strips of metal 22 whichmay have proJecting ears 23 at. the upper and lower ends thereof. I

As shown in Figs. 6, 7 and 8, these projecting ears 23, when the sheetmaterial has been rolled in the form ofa hollow cylinder, are turnedover adjacent laminations or layers to hold the same together. As shownin Fig. 8, when the head 4 is placed in position, the tapered groose 6engages the ears 23 therebetween.

In Fig. 9 the bolt 24 is at one end attached to the body portion, theother end passing through the adjacent head where its end is providedwith a winged nut 25. In this case, there may be a plurality of bolts 24spaced` around the. container as desired, both at lthe upper and loweredges.

In Figs. 10, 11, 12 and 13 I have shown a modified form ot container inwhich the heads and the body portion are rectangular in shape. In thismodification the head portion functions in substantially the same way asit would for a cylindrical container. The body portion, such as 30, maybe formed .of any suitable material, such as the lamihesive or by meansof ears, such as the ears 23 previously mentioned with respect to thecylindrical body portion. The closure portion is of suitably formedmetal having its central portion disposed below the level of the outeredges in yorder that the fastening means will ordinarily lie below thelevel of the top edges of the closure, to prevent breakage or injury tothe fastening means. The body portion such as 31 is in the form of arectangle and provided with reinforcing 0r strengthening ribs 32. Alongthe rectangular edges of this body portion are the outer flange 34 ofthe cylindrical provided tapered flange portions 33 and 34. Thereisformed between these flanges 33 and 34 a tapered giioove such as 35which is of rectangular form and is adapted when the ,closure portion 31is placed over the edges of vthe body portion 30 to grip the edges of l'the body portion in a manner identicall the closur and the body portionpreviously mentione The center portion of the closure 3 isprovided"`with an aperture 36 through which a bolt 37 extends and whichon its upper end is provided with a winged nut 38. This bolt andanutfastening means is identical with the vfastening means previouslymentionedwith respect to the body portion. When the two closure portionsare fastened into place they provide a rigid, compact receptacle inwhich the plates are held down under a predetermmed and continuinglpressure which makes the receptacle one which can resist sudden shocksand which will preserve its strength even after shocks. v

As'shown in Fig.\12, the body portion when assembled may be provided atoney or more of its corner portions with an angular plate such as 39which may extend from the top to the bottom edges. The upper and lowerends of this plate 39 are adapted to be gripped between the body portionand closurel portion. This plate is added to provide additionalreinforcing strength to the receptacle.

In Fig. 13 the body ortion 30 is shown collapsed into the form 1tassumes when not in use and when it is to be shipped. It will beobserved that this collapsed form takes up very little space and itwill, therefore, be understood that the entire container, including allits parts, when collapsed can be packed and shipped vin much smallerspace than when assembled. The different types of fastening meansmentioned previously with respect to the cylindrical form of containerare equally adaptable to use in connection with this rectangularcontainer, and

it is to be understoodwithout further refern similar to'the grippingbetween,A

being subjected to' ence that they may in this manner be so use( Itwill, therefore, be observed that I have provided a simple, compact andstrong container which can be readily assembled and very easilycollapsed or disassembled, and when collapsed will occupy a very smallspace compared to the assembled volume. This permits of the eiiicientstorage of large numbers of these containers and also permits of theready and economical shipment of large numbers of these containers,which has not hitherto been possible. The particular trusslike grippingaction between the heads and the body portions in the manner heretoforedescribedpermits this container to have a strength far beyond anyheretofore used or known. Minor modifications may, of course, be made inthe form and arrangement of the parts and the structure withoutdeparting from the spirit of the invention. f

What' I claim is:

1. A container, formed of a plurality of.layers, removable heads on theends of the body, said heads having at their margins tapered and spacedfianges forming inverted V-shapedl grooves, said .grooves being of asize less than the thickness of the body, and means for drawing theheads together whereby the ends of the body will be forced into thegrooves of the heads with a wedging action and a tight joint therebyobtained.

2. A. container, comprisin a hollow body formed of a sheet composed of aplurality of layers, said sheet having at its ends reinforcing 'stripsprovided with ears projecting beyond the edges of the sheet and bentover the said edges to clamp the several layers of the sheet together,and removable heads on the ends of the body and having at its margin aV-shaped groove ofa size less than the thickness of the body, and meansfor securing the heads on the body, said means serving to draw the headstogether to force the ends of the body into the grooves with a wedginaction.
